s claims. (C l. en -3s) The present invention relatesto apparatus fortreating thread or yarn and more specically pertains to an arrangementfor applying moisture or liquid to the thread ordyarn as the same iswound on a thread carrier or bobbin.

An object of theJ invention resides in providing means for supplyingconditioning liquid to yarn as the yarn is being wound on a rotatingcarrier member or bobbin so that the conditioning liquid will besupplied to each layer of yarn wound on the carrier member.

A further object of the invention includes means for supplying moistureto thread as. the

thread is wound on a bobbin including means for varying the quantity ofliquid supplied to the thread. 1

A still further object of the invention resides in providing a brushhaving bristlesvwith the brush mounted to engage the thread being woundon the bobbin including means for supplying conditioning liquid to thebristles of the brush whereby the liquid is transferred to the thread asthe same is wound on the bobbin.

A more speciilc object of the invention pertains .with thread wound onthe thread carrier and means for swinging the brush away from the threadcarrier when rotation thereof is stopped.

Other objects and features of the invention will be more apparent upon aconsideration of the accompanying drawing and the following de scriptionwherein. an exemplary embodiment of the invention is disclosed.

In the drawing: Fig. 1 is a diagrammatic view partly in sectionillustrating the general organization of apparatus embodyingtheinvention.

Fig. 2 is an end elevational view of the lar 4 rangement shown in Fig.1.

Fig. 3 is an enlarged plan view of the brush with parts thereof broken.away to illustrate means for supplying liquid to the bristles.

Referring to the drawing there is shown at Il a carrier member or .abobbin of a conventional type suchy as employed in some types of wind-The carrier' member Il is preferably arranged with the axis thereof in ahorlzontal, manner as shown in Fig. 1. The thread or yarn carrier orbobbin is rotated by means of a driven shaft i i. The shaft Il is drivenfrom a suitable power source as i's lcustomary in winding machines.Power is transmitted from the shaft il to the shaft I2 through a clutchmechanism indicated generally at I4. Thus, the thread carrier I0 may berotated by moving the parts of the clutch i4 into driving engagement andthe bobbin l will of course be stopped when the shaft I2 is de-clutchedfrom the shaft Il.

A thread or yarn I'Ijlto be wound on the car. rier member I0 extendsthrough suitable tension means diagrammaticallly illustrated at It inFig. 2. The thread I1 after passing through the tension means Il iswound on the bobbin Il in the i direction of thev arrow shown in Fig. 2.'I'he thread I1 is also guided or bodily moved longiyarn is arranged onthe bobbin II after which vanother layer is wound on the layerpreviously wound on the bobbin.

- to the thread or yarn as the same is wound on the bobbin Il. Suchmeans may for example include a brush shown generally at Il havingbristles Il for engaging the thread or yarn wound on the bobbin Il. Thebrush is preferably mounted above the thread carrier il as shown in Fig.2. Thus. the brush which is suptoning liquid will flow or creepdownwardly on the bristles It.' 'I'he brush Il is also mounted in such amanner that the bristles will engage the bobbin `or the thread thereonand the bristles preferably extend in the rotating direction of thethread carrier Il. In other wordsthe bobbin lIl is rotated in aclockwise direction when the bristles are arranged above the carriermember as shown in Fig. 2.

vThe brush may be formed of a substantially rigid-pipe 2l rotatablymounted in suitable brackets 22 which may be supported on the windingapparatus. The bristles may extend into the pipe 2| as shown in Fig. 3.A suitable casing Il may be provided for enclosing portions of thecapillary action of the wick 3|.

bristles adjacent the pipe 2I. This casing 23 is suitably secured to thepipe 2 I The moistening apparatus includes means for supplyingliquid tothe bristles I9. Such means may include a tank 26 for storing a quantityof conditioning liquid therein. The tank 26 is arranged to be raised orlowered with respect to the position of the brush I8 by any suitablemeans such as a threaded shaft 21 and a handwheel 28. The tank 26 may beconnected to the pipe 2| by means of a flexible tube 29 to permitrelative movement between the pipe 2| and the tank 26. Thus, by raisingthe tank'26 more liquid will be supplied to the bristles I9 since thepressure of the liquid within the pipe 2| will thereby be increased.Likewise, less liquid will be supplied to the bristles of the brush whenthe handwheel 26 is rotated to lower the tank 26. The vertical movement-of the tank 26 thus provides means for varying the amount of moistureconveyed to the thread or yarn being wound on the bobbin I6.

The arrangement may include wick means within the pipe 2| and a wick 3Imay extend therefrom through the exible tube 29 into the tank 26. Thewick 3| will thus absorb a supply of the conditioning liquid from thetank 26 and retain the liquid so as to make the moisture available tothe bristles I9. With such an arrangement and when the tank 26 is raisedwith respect to the brush I8 the wick 3| will be saturated at a fasterrate thereby feeding more liquid to the bristles which in turn willsupply a greater quantity of the liquid to the yarn on the surface ofthe carrier member I0. By lowering the container 26 the saturation ofthe wick will be reduced and consequently the transfer of liquid bymeans of the bristles I6 onto the surface of the thread or yarn on thebobbin I6 will thereby be reduced. Even when the tank 26 is moved to aposition Ibelow the level of the brush I8 liquid will nevertheless beconveyed to the bristles I3 by The quantity of liquid applied t thethread being wound on the bobbin I0 may be further controlled by varyingthe speed of the rotating thread carrier.

y When the rotation of the bobbin I0 ceases 'it is advisable to removethe brush with the bristles I9 thereof from engagement with the threador yarn on the bobbin. Any suitable means may be provided for moving thebrush I8 to a position preventing the bristles I3 from transferringmoisture tothe thread on the bobbin. Such means for example may includea handle 32 which is mounted to rotate a shaft 33. A bevelled gear wheel34 suitably keyed to the shaft 33 will be rotated when the handle 32swings in the directionof the arrow 36. Such rotation of the gear 34will rotate a beveled gear wheel 31 secured to the pipe 2| so as torotate the rigid pipe in the brackets 22 and swing the brush I8 awayfrom the bobbin I6. A lever 36 is also pivoted with the rotation of theshaft 33 by the handle 32 to de-clutch the shafty I2 from the shaft II.For this purpose one part 4| of the clutch is provided with acircumferentially extending groove into whicha lug carried by thelever38 extends. The groove in the member 4I may be sufficiently large topermitl such swinging movement of the lever 38. Thus, when the shaft I2is (ie-clutched from the shaft II to stop the bobbin I0 thebrush I8 willbe removed to a position -where the bristles I9 will no longer engagethe threadvon the bobbin I0. F v

The invention also includes automatic means for moving thebrush I 8 toaposition for preventing liquidv from being transferred to the thread onthe carrier member I0 when the yarn breaks or in the absence of threadtension. Such means may include a feeler arm 43 pivotally mounted toswing on a pin 44. Thus, when the thread I1 breaks or in the absence oftension thereon the feeler arm 43 will swing downwardly in Fig. 2. Asuitable arrangement for swinging the Ibrush I8 or rotating the pipe 2|when the thread I1 breaks or in the absence of tension may include anelectromagnet 46 which is supplied with current from a suitable sourcesuch as a battery 41 when the contacts 48 are closed by the downwardswinging movement of the feeler arm 43. When the electromagnet 46 isenergized an armature 5I thereof will be drawn into the coil of theelectromagnet-l to swing the lever 36 to thek left in Fig. 1 and rotatethe shaft 33 in a clockwise direction. Such rotation of the gear 34 willcause the gear 31 to be rotated and swing the brush I 8 away from thebobbin I6. The armature 5I being connected to the lever 38, the clutchmember 4I will also be moved to the left to interrupt the drivingconnection' between the shafts I I and I2 and thus stop the bobbin Iwhen the thread breaks or in the absence of tension.

The brush I8 is preferably mounted above the bobbin I6 so that the brushwill normally swing downwardly to lay on the thread carried by thebobbin. Yieldable means, however, may be provided for more positivelymoving the bristles I3 of the brush into engagement with the thread oryarn being wound on the ythread carrier. Such yieldable-means mayconsist of a relatively light torsion spring 56 biasing the brush into aposition whereby the bristles I9 engage the thread on the bobbin I0.

'I'he means for supplying liquid to the bristles I9 of the brush may beconstructed as shown in Fig. 4 wherein a plurality of small wicks 3|aare arranged within the p ipe 2l and these'wicks may also extend intothe tank 26.
